The 5th embodiment
Below, the fifth embodiment of the present invention will be described.
Figure 20 A is the audio frequency among the 5th embodiment and/or the I/O opertaing device 38 of video data recording and replay device 3 to Figure 20 D iApplication drawing with data management apparatus 34 (Fig. 4).Notice that in the 5th embodiment, the data length of each module is for example 10 megabyte.
For example, at audio frequency and/or video-unit 4 iEdit package be contained in the raw data A shown in Figure 13 A among the 3rd embodiment to D and the partial data A of data length with 40 modules, 5 modules, 40 modules and 5 modules to D (Figure 20 B) and obtain under the situation of the editing data shown in Figure 13 B, the editing data shown in Figure 17 B is from audio frequency and/or video-unit 4 in the 4th embodiment iThe I/O opertaing device 38 of input audio frequency and/or video data recording and replay device 3 i
I/O opertaing device 38 when the audio frequency shown in the 4th embodiment and/or video data recording and replay device 3 iFinish when handling to the editing data of D and record entry according to the raw data A shown in Figure 17 A, obtain the playback inlet of the editing data X shown in Figure 17 C.
Yet it is short like this that the data length of the partial data of raw data B and D (partial data B and D) has become 5 modules.When playback had with the audio frequency of such editing data identical content and/or video data, the start-up portion of the decline of each partial data A and C and each partial data B and D was recorded in the recording areas of separating of the recording medium of record and replay device 24.Therefore be necessary the remote recording areas and the wait rotation of the recording medium of Visitor Logs and replay device 24 in the playback end of partial data B and D.On the other hand, each partial data B and D have the so little data length of 5MB, so I/O opertaing device 38 iMemory buffer 222 (Fig. 8) to suffer underflow and wait for to rotate in being used for the request time of access be possible.When underflow took place memory buffer 222, resetting continuously, it was impossible to become.
Audio frequency among the 5th embodiment and/or video data recording and replay device 3 are target to solve such problem.
Have the partial data that possibility causes the short data length of memory buffer 222 underflows, the I/O opertaing device 38 of the 5th embodiment for resetting continuously iAnalysis is from audio frequency and/or video-unit 4 iThe editing data (Figure 17 B) that receives, the short partial data of continuous recording also will be lacked the booking situation district that partial data is recorded in the recording medium of record and replay device 24 in advance, obtain not cause the data length of memory buffer 222 underflows, so just avoid top deficiency.
Note the I/O opertaing device 38 of the audio frequency of the 5th embodiment and/or video data recording and replay device 3 iOperation, that is, remove I/O opertaing device 38 iThe memory contents of ROM382 outside, the audio frequency of parts and the 4th embodiment and/or the parts of video data recording and replay device 3 are identical.
Below, will explain the audio frequency among the 5th embodiment and/or the I/O opertaing device 38 of video data recording and replay device 3 tout court by example iProcessing.
As mentioned above, the 100th module to the 189 modules at the recording medium that is recorded in record and replay device 24,269 of the 200th modules to the, the 300th module to the 379 modules, and the raw data A of the 400th module to the 469 modules is between the D (Figure 20 A), the 110th module to the 149 modules (data length: 40 modules), the 220th module to the 224 modules (data length: 5 modules), 40 modules) and the 420th module to the 424 modules (data length: 5 modules) be included in the editing data as partial data A the 330th module to the 369 modules (data length: to D (Figure 20 B).
For example, because data length is 10 modules or littler and may take place under the situation of memory buffer 222 (Fig. 3) underflow, when replayed portion data B and D, there is the possibility that to finish continuous playback.On the other hand, shown in Figure 20 B, even partial data A and C be divided into partial data A ' with data length 35 modules and C ' and have the partial data a of data length 5 modules and during c when replayed portion data A ' times, might reset continuously and not have obstacle.
By realizing this point, the I/O opertaing device 38 of the 5th embodiment i Control control system 20, partial data a and c are placed on the short partial data B shown in Figure 20 C and D front obtaining partial data ab and cd with data length 10 modules, and they are recorded in booking situation district (the 1000th module to the 2000 modules for example of the recording medium of record and replay device 24 in advance; The compiling recording areas).
Further, shown in Figure 20 D, for partial data A ', ab.C ', and cd, it produces the playback inlet identical with the 4th embodiment and it is outputed to data management apparatus 34.Data management apparatus 34 should be reset to enter the mouth and be stored in RAM344 and it is recorded in management record data equipment 36.
At audio frequency and/or video-unit 4 iRequest I/O opertaing device 38 1To 38 nIn any one playback Figure 13 B shown in the situation of editing data under, receive the I/O opertaing device 38 of request 1To 38 nThe playback inlet of the equipment editing data that is requested to reset to data management apparatus 34 request.Data management apparatus 34 will be reset to enter the mouth according to this request and output to the I/O opertaing device 38 of request playback inlet 1To 38 nAn equipment.Receive the I/O opertaing device 38 of the inlet of resetting 1To 38 nAn equipment according to the playback inlet that receives reset audio frequency and/or the video data identical with editing data.
In this mode, by the partial data that has the amount that does not cause memory buffer 222 underflows at compiling recording areas record in advance, also partial data by being recorded in the general record district and the partial data that is recorded in the compiling recording areas produce the inlet of resetting, and according to audio frequency and/or video-unit 4 iFigure 20 D of request unanimity shown in the playback inlet reset from partial data A ', ab, C ' and the cd of record and replay device 24, except that the function of the fast speed playback of the audio frequency shown in the 4th implements and/or video data recording and replay device 3, can also realize the continuous playback of audio frequency identical and/or video data with editing data.
Shown in Figure 20 D, here, the deletion enable flag value of partial data that is recorded in the compiling recording areas is ON and the deletion enable flag value of other partial datas is OFF, the reason that the deletion enable flag is set to the value shown in Figure 20 D is, even deletion record is in the data of compiling recording areas, because initial original data record is in record and replay device 24, so it will can not lost.
Note, under the situation of data length of partial data A and C,, can realize continuous playback thereby then produce the inlet of resetting by partial data B and D being increased to partial data A and C and it being recorded in the compiling recording areas less than 15 modules.
Further, even increase partial data A and C and partial data B and D, under the situation of data length of each less than 10 modules, by before partial data A, also increasing the partial data (not shown) to partial data A and B, after partial data D, increase the partial data (not shown) to partial data C and D, perhaps whole partial data A is being compiled recording areas to the D continuous recording, can realize resetting continuously.
Further, even be not right after partial data before current data, but the portion after current data of being right after sends out the part of data and is increased to short partial data, also can obtain same effect.
At the 5th embodiment, the short partial data explained is above thought process of compilation with being right after the processing that part or all of partial data before current data is recorded in the compiling register in advance.
